CHECK-VALVE.

Specification of Letters Eateni..

"tatented Der. iet, 19th?.

Application filed December t), 1904. Serial No, 236,213.

1'0 all whom it may concern:

Be it known that l, Janes G Paniieia a citizen of the l'nited States of America, residing at \\'tisliiiigt ii'. in the county of Vivashington and State ot' Pennsylvania. have invented certain new and useful lmprovenients in Cheek-Valves, of which the toliowing is :i specification, reference heilig had therein to the accompanying drawing.

l`hi.-; invention has relation to check valves, and the invention has for its object the provision ot novel means for cleansing valves of thisclniracterand saine more etlieient when used.

Another ohject ot' this invention is to provide a valve ot' the ahove type which will he extremely simple in construction., strong and du 'ahle and con'iparatively inexpensive to nninutacture, and l have so constructed my improved valve that it may he readily disassembled and the wearing parts re.- newed when they have heroine worn.

Brielly described, my improved valve con sists' ot a T-sliaped hotly portion having au inlet, an outlet and a cleansing port. and in the cleansing port, l pivotally mount a valve, which, in ite` normal position, is adapted to close one ot the ports olf the hotly, and in the top of the cleansing port l secure a suitahle cap.

The construction ahovc described will he hereinafter more fully set toi-th, and referring to the drawing accompanying this application, .Figure l.l if; a side elevation ot iny in'iproved check valve. lf'ig. 2 is a longh tudinal sectional view ol the saine, and lfig, 3 is a vertical traiisvei'se sectional view taken on the line. w-af ot Fig. 2.

Throughout -the several views of this drawin, similar reference characters designate corresponding parts, and my improved check valve as constructed. in accordance with my invention, consists ot a T-shaped hody portion or shell t having an outlet port 2, an inlet port Il and a cleansing port ft. l`hcliorizontal portion ot my improved valve is provided with the enlarged hexagon shaped collars` 5, 5 and upon the cud oi the check valve which hasl the outlet port 2i thereon, are screw threads as indi l formed rendering the cated :it t3, and the inlet port is interiorly screw threaded as indicated at l.

ln 'forint e' the inlet. port, l provide :in

annular flange S in the hotly portion o the check valve, and the tace ol the tlange is inclined as clearly .shov n in liig. ot' the drawing. The cleansing port or the vertical portion olt thc. valve hody is machined to torni a seat 5t, and is provided with .screw threads as indicated at lt), wliei'ehy a cap having a recessed lower portion ll may he secured in this vertical portion ot the valve body, 'l`lie cap has termed integral with it the hexagon nut l2 whereby the cap may he easily removed 'and placed on the valve. The cleansing port -l near the seat El has recesses l-il', l-l termed therein, these recesses heilig Vtornied opposite each other and to one side and parallel with a transverse axial line drawn through said cleansing port. In the recesses let, tel are pivotally mounted the pins l5, l5 carried by the yoke 16, this yoke having `formed integral therewith, an upwardly extending lug 17, and between the .sides of the yoke is pivoted by alpin 18, an arin 1li) which has` formed integral with its lower end a valve 20, the yoke lo in connection with the pins i5 thus serving as a swing link hetween the valve 2() and the transverse pins 143-15, and insuring the uniform seat ing ot the valve. '.l`lie valve preferably circular in torni and has its lower edge weighted by an enlargement 21. acting as a .stop-lug and adapted to engage the side ot' the shell l.

ihen'a supply of water enters thepoi't the valve 2() is raised, which will permit the water to pass through the outlet port 2,

hut should said water supply he unexpectedly eut olf or reduced the pressure otl water which has passed through the outlet port 2, or' the hack llow ot' the saine, will cause the valve 2t) to seat itselt upon the annular flange 8 and prevent the water thatl has passed by said valve from again reentering the inlet port f3. By providing the screw threaded cap ll the saine may he removed to cleanse the valve hotly of all sediment and ingredients foreign to the operation of the valve 2t) or said valve may he raised out of the valve casing hy gripping the lug t7 :and removing the pins l5, l5 t'roin their respective recesses. 5y pivoting the valve 2O tothe swinging link lo, the valve is permitted to he opened and closed without causing the eonihined link and yoke to rotate upon its axis, this construct ion preventing the parts, willi the exception ot the valve, from wearing, and reducing the wear and tear upon valves of this character to a minimum.

lt will he noted that various changes may he. iuade in the details of construction without departing from the spirit of the invena vertical plane passing through the Valve tion. l seat, pins pivotally mounted in said recesses,
